我是 android 开发和 stackoverflow 的新手,所以请放轻松。;)
我创建了一个包含多个 TextView 的 ViewGroup。特别是有一个 switch case,其中 case 常量是我的 java 对象中定义的整数。然后,我将 case 语句设置为我认为是 String 值的值。最后我使用 setText() 方法将 TextView 对象设置为这个字符串。我遇到的问题是,实际上返回到视图的是与案例相关联的整数,而不是文本值。这让我相信我传递给 TextView 的是一个 int 但我不知道如何或在哪里可以纠正这个问题。
任何帮助将不胜感激。
ViewGroup 代码在这里:
public View getView (int position, View convertView, ViewGroup parent)
{
ViewGroup listItem;
if (convertView == null) {
listItem = (ViewGroup) getLayoutInflator().inflate(R.layout.list_item, null);
}
else {
listItem = (ViewGroup) convertView;
}
MovieInfo movieInfo = list.get(position);
TextView movietitleText = (TextView) listItem.findViewById(R.id.movietitle_text);
TextView directorText = (TextView) listItem.findViewById(R.id.director_text);
TextView producerText = (TextView) listItem.findViewById(R.id.producer_text);
TextView releaseyearText = (TextView) listItem.findViewById(R.id.releaseyear_text);
TextView genreText = (TextView) listItem.findViewById(R.id.genre_text);
movietitleText.setText(movieInfo.getMovietitle());
producerText.setText(movieInfo.getProducer());
directorText.setText(movieInfo.getDirector());
releaseyearText.setText(movieInfo.getReleaseyear());
String genreName;
Resources resources = context.getResources();
switch (movieInfo.getGenre()) {
case MovieInfo.GENRE_ACTION:
genreName = resources.getString(R.string.action_label);
break;
case MovieInfo.GENRE_COMEDY:
genreName = resources.getString(R.string.comedy_label);
break;
case MovieInfo.GENRE_DRAMA:
genreName = resources.getString(R.string.drama_label);
break;
case MovieInfo.GENRE_FAMILY:
genreName = resources.getString(R.string.family_label);
break;
case MovieInfo.GENRE_HORROR:
genreName = resources.getString(R.string.horror_label);
break;
case MovieInfo.GENRE_ROMANCE:
genreName = resources.getString(R.string.romance_label);
break;
default:
case MovieInfo.GENRE_UNKNOWN:
genreName = resources.getString(R.string.unknown_label);
break;
}
genreText.setText(genreName);
return listItem;
}
case 常量在我的 java 对象中定义:
public static final int GENRE_UNKNOWN = 0;
public static final int GENRE_ACTION = 1;
public static final int GENRE_COMEDY = 2;
public static final int GENRE_DRAMA = 3;
public static final int GENRE_FAMILY = 4;
public static final int GENRE_HORROR = 5;
public static final int GENRE_ROMANCE = 6;
private String movietitle;
private String director;
private String producer;
private String releaseyear;
private int genre;
选中复选框时设置流派的操作位于此处的主要活动中:
if (actionCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_ACTION);
if (comedyCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_COMEDY);
if (dramaCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_DRAMA);
if (familyCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_FAMILY);
if (horrorCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_HORROR);
if (romanceCheckBox.isChecked()) movieInfo.setGenre(MovieInfo.GENRE_ROMANCE);
Strings.xml 的一部分在这里:
<string name="movietitle_label">Movie Title</string>
<string name="director_label">Director</string>
<string name="producer_label">Producer</string>
<string name="releaseyear_label">Release Year</string>
<string name="genre_label">Genre</string>
<string name="action_label">Action</string>
<string name="comedy_label">Comedy</string>
<string name="drama_label">Drama</string>
<string name="family_label">Family</string>
<string name="horror_label">Horror</string>
<string name="romance_label">Romance</string>
<string name="unknown_label">Unknown</string>
<string name="ok_label">OK</string>
<string name="clear_label">Clear</string>
<string name="showdatabase_label">Show Database</string>
<string name="id_label">ID</string>
<string name="select">Select Year</string>
谢谢你的帮助!
